Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Bones that are longer than they are wide; most of the limb bones are in this category.






2. An immovable joint; also known as a synarthrosis. The bones are firmly united by fibrous tissue; includes the sutures between the skull bones.






3. Skull bones that are part of the internal bones of the face; support part of the lateral walls of the pharynx.






4. The immovable fibrous joints that unite most of the skull bones; also known as synarthroses.






5. The main - weight - bearing bone of the lower leg; forms the stifle joint with the femur proximal to it and the hock with the tarsus distal to it.






6. The central canal that runs the length of a haversian system; contains blood vessels - lymph vessels - and nerves that supply and nourish the osteocytes.






7. The mineralization or hardening of bone.






8. Mature bone cells located in lacunae.






9. The sievelike area of the ethmoid bone through which the many branches of the olfactory nerve pass from the upper portion of the nasal cavity to the olfactory bulbs of the brain.






10. A bone of the sternum.






11. The first - most cranial sternebra.






12. The paranasal sinus in the sphenoid bone; only present in horses.






13. The smooth joint surface of a bone that contacts another bone in a synovial joint.






14. The bones of the neck portion of the spinal column.






15. A freely moveable joint; also known as a diarthrosis.






16. The large process on the proximal end of the ulna that forms the point of the elbow; the site where the triceps brachii tendon attaches.






17. One of two bones (the radius is the other) that form the antebrachium - or forearm; forms a major portion of the elbow joint with the distal end of the humerus.






18. A toe made up of two or three boens called phalanges.






19. A depressed or sunken area on the surface of a bone; usually occupied by muscles or tendons.






20. The single - dorsally projecting process of a vertebra.






21. Skull bones that are the bones of the ear; three pair of bones in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear.






22. The cartilaginous joint (amphiarthrosis) that unites the two halves of the pelvis ventrally. Also called the pubic symphysis.






23. One of countless tiny channels through the matrix of bone that bring blood in from the periosteum to the haversian canals in the centers of the haversian systems. The haversian systems run lengthwise in long bones while these canals come in at right


24. The main growth area of a bone developing by endochondral method; areas of bone development that are located in the main portions of the cartilage rod bone templates in the developing fetus.






25. Skull bones that are external bones of the cranium; form the dorsolateral walls of the cranium. They are large and well developed in dogs and cats - but small in horses and cattle.






26. Another term for the diaphysis of a long bone.






27. The kneecap; the largest sesamoid bone in the body; located on the front surface of the stifle joint in the tendon of the large quadriceps femoris muscle. It rides in the trochlea of the femur.






28. The upper arm; the area of the thoracic limb between the elbow and the shoulder.






29. Bones present in some tendons where they change direction markedly over joints; act as bearings over joint surfaces - allowing powerful muscles to move the joints without the tendons wearing out as they move over the joints.






30. The fluid - filled potential space between the joint surfaces of a synovial joint; normally filled by synovial fluid.






31. The process of a vertebra that forms a synovial joint with an adjacent vertebra.






32. The hormone secreted by the parathyroid gland that prevents the level of calcium in the blood from getting too low.






33. Long - faced. Example: Collie.






34. The visceral bone in the heart of cattle that helps support the valves of the heart.






35. The most caudal rib or two in the rib cage; a rib whose costal cartilage does not unite with anything but rather ends in the muscle of the thoracic wall.






36. Process on the cranial end of the second cervical vertebra (axis) that fits into the caudal end of the first cervical vertebra (atlas).






37. A longitudinal ridge on the front of the proximal end of the tibia.






38. The front limb.






39. Skull bones that are part of the internal bones of the face; also known as the nasal conchae. Four thin - scroll - like bones that fill most of the space in the nasal cavity.






40. The process on the distal end of the distal phalanx of dogs and cats that is surrounded by the claw in the living animal.






41. An arthrodial joint in which two flat articular surfaces rock on each other; the carpus is an example.






42. Small bones shaped like cubes or marshmallows; an example are the carpal bones.






43. A general name for a lump - bump - or other projection on a bone; can be articular processes or nonarticular processes - which are usually sites where tendons attach.






44. Bones that are relatively thin and flat; they consist of two thin plates of compact bone separated by a thin layer of cancellous bone. Includes skull bones and the scapula.






45. A spheroidal articular surface on the proximal end of a long bone; present on the proximal ends of the humerus - femur - and rib. Joined to the shaft of the bone by an area that is often narrowed and called the neck.






46. The 'forearm' region of the thoracic limb.






47. A thin bone located beside the tibia in the lower leg region of the pelvic limb. It is a complete bone in the dog and cat - but only the proximal and distal ends are present in horses and cattle. It doesn't support any appreciable weight - but acts a






48. The bones of the pelvic limbs located between the tarsus and the phalanges.






49. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.






50. The solid structure formed by the fusion of the sacral vertebrae.
